I have cardinal tetras, ember tetras, rasbora agilis, gold ring danios, von rio tetras, danio shanensis and probably a few otehrs I am forgetting in teh mid sized range (1"-2.5")
I brought back a mixed bag of small tetras from my last collecting trip - just kept ever tetra that was about a 1/4" long to see what would grow out. I have a group of about ten 2" tetras I don't plan to keep that are yours if you pick up (I'm in Reston). My research has resulted in the conclusion that none are scientifically described. I also have several groups that are smaller that I'm holding to breed - again with these none are scientifically described.
